Abstract

A seal consists of an annular thermoplastic body having a relatively thinner annular base and a relatively thicker, compressible annular bead. The annular body has a shape that corresponds to a mounting surface of a loudspeaker. A surface of a rim of a loudspeaker basket is placed in contact with a mold to form a substantially annular cavity, a melted thermoplastic material is injected at low-pressure into the cavity to form a seal adhered to the surface.
